DoUGH-mvmine MACHINE.

To all whom it may concern:

'Be it known that I, FRANK HOUTEN, Jr., a citizen of the United States, residing at Fishkill-on the-Hudson, in the county of Dutchess and State of New York,

have invented certain new and useful Improvements in Dough-Dividing .Machines;

and I do hereby declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanydough, the specific embodiment of'the in vent on disclosed herein being particularly adapted for use in such'machines as are illustrated in prior Patent No; 788,123, and in co-pending application Serial No. 632,853, filed June 18, 1911, but it will be obvious that'the invention is applicableto. any Ina chine'of a type wherein movable measuring pockets are employed with positively actu ated pistons for ejecting the measured quantities of dough.

In the accompanying drawing, Figure 1 is a longitudinal, horizontal section through the cylinder and connected parts of a machine embodving the features of the present invention, portions of the cylinder "being" nected by a slmilar bar.

cally opposite sides ofthe cylinder and in any number proportioned to the capacity of the particularmachine. An axial shaft 8 extendsthrough the cylinder and is journaled in the, ends thereof, and extends beyond the journal 2. Shaft 8 carries gear wheels 9, 9, 'splined to the shaft 'within'cylin der land meshing with diametrically oppositely arranged sliding racks 10, 10, there being a pair of such racks for each gear wheel9, one-rack being arranged relatively atone side of; the longitudinal planes of shaft 8, and the other at the opposite side thereof for eac'hgear 9, the inner end portions of the raclrs extending across said From-this posltion the racks are planes. adapted in operation. to be moved longitudinally, with respect to themselves, by rotation of the gear wheels 9 inwardly in a transverse-axial direction.

7 Obviously, since movement of the gear wheelswill shift the racks, shifting of the racks will rotate the gear'wheels. To insure synchronism in the movement ofall the parts, these racks '10 which are, above the gear wheels are con- .nectedby an axially extending bar 11, and

the racks lO below the gear wheels are con- Within 1 each pocket 7 is arranged the usual measuring and ejecting piston 12,

each of saidjp'istons having an lnner terminal, preferably reduced, cylindrical shank 13 extending through a portion of the web of oneof the bars 11, the said web being being omitted. Fig. '5 is a detail end view i ofthe threaded sleeve. Fig. 6 is a transverse, vertical section taken onthe plane indicated by line 66 of Fig- 1 and looking I in the direction of the arrow.

' Similar characters of reference in the several figures indicate the same parts.

The measuring cylinder 1 is provided -'witli tubular journals 2 and 3 r'otatably ratchet 'mechanism mounted in the frame 4, the ournal 3 being connected with the ratchet of pawl and f5 [actuated by the sprocket 6 by driving means not shown, but such as is illustrated in my above-mentioned prior patent, for imparting an intermittent rotary movement to thecylinder 1. Jourformed with a bore or pocket 14 forthe respective piston inwhich is arrangeda plunger 15'whose inner end is'adapt'ed to "ger 15 is providedwith a head 18 for facilitating being grasped manually and drawn j longitudinally away fromshank 13 for releasing the same and allowing withdrawal of the "respective piston forenabling easy cleansing of the parts.

The detachable engagement of the plungers 15 with pistons ioo j 12 while facilitating ease of application and removal. of the pistons, insures, during use, unity of movementof the respectlve plstons with the racks 10.

A- nut 19 is detachablysecured to the JOHFIiHl 2, by screws or bolts 20, and is provided with threads intermeshing with the threads of a sleeve 21, the threads being of. a verycoarse pitch so as to serve as a cam for shifting the: sleeve .21" longitudinally duringrelative rotation of the sleeve and nut. The sleeve 21 is keyed to shaft 8so as the slide freely axially thereof while con-1.

. fined, to rotate therewith. The laterally outstanding arms 22 are fixedto the outer end of sleeve 21 for cooperating with. detents hereinafter described. r

A yoke 23 is fixed to the frame 4: and has its arms inclosing aportion of the bearing 2', the outer end of the yoke being provided with a clamp bearing 24 engaging and adv.j-ustably retaining in position the tubular shaft 25 of a disk 26 and the said disk being arranged within the yoke and being pro "vided with inwardly extending arms. or horns 27 fixed to or formed integral with the inner face of disk 26. The arms 27 constitute the detents' for arms 22 and are adaptechin operation, to interlock therewith for-enabling relative rotation of shaft 8 independently of sleeve 21 as will hereinafter become more fully apparent. Axially slidablewithin the bore of shaft 25 is a sleeve 28 which is threaded onto a shaft 29 extend-' I ing axially through the end of shaft 25 and being provided with a journal in shaft 25,

i V the outer portion of shaft 29 being engaged I by an operating wheel 30 for enabling manual rotation of shaft 29 whereby the sleeve 28 may be reciprocated axially. Oppositely disposed radial arms31, 32 arefixed to the inner portion of the sleeve'28, and one of said arms is provided with an eye slidingly I surrounding andguided by pin- 33 fixedly mounted in yoke 23. 2 An indicator arm 3% I is pivoted at its lower extremity on a pin 35 fixed on the respective side of yoke 23, the indicator arms extending from the pivot 35 to a position {relative to a grachialscale 36 formed on a plate fixed to yoke 23for indicating the relative distance of adjustment of the arm which of courseis proportioned to the distance of adjustment of sleeve 28, and as sleeve 28 is in axial aline'ment with the threaded sleeve 21, the position of sleeve 28 is adapted tofcontrol the extent of axial movement of'sleeve 21." A yoke-or longitudinal slot is formed inthe length of indicator arm 34 through which extends the outer terminus of arm 32 so, that arm 34 is moved with sleeve 28 when the sleeve is ad-' jus ted'for varying'the extent of possible movement of sleeve 21, and the limits of movement of sleeve 21 with the resulting limit in capacity of the dough receiving pockets are indicated by the position as 'sumedby arm 34. a

In operation, the parts being in 'the position indicated in Fig. 3, dough is forced into the pockets 7 at one side of the cylinder 1 by the usual plunger or other power means. The piston 12 of the pockets being filled areforced: inwardly by the incoming dough and the movement of the piston effects the corresponding movement of racks 110which revolve gears 9 and thus revolve shaft'8. As sleeve 21 revolveswith shaft 8 and nut 19 remains stationary, the sleeve will be given an axial thrust which is suffiaxial thrust of sleeve 21 is effected by thethreads of the sleeve and continues until the outer end of the sleeve strikes the inner end of sleeve 28 whichlatter sleeve is adapted for axial adjustment by operation "of wheel 30 to any desired extent and such adjustment is indicated by. the arm34, the

- '-graduations 36 serving to indicate the result of the adjustment since the limit placed on the axial movement to sleeve 21 places a proportional limit on the possibility of inward-movement of pistons, 12.

As soon as the pistons 12 reach the limit of their in ..-ward movement, the cylinder 1 is. given a ,half revolution and during the first portion of'such revolution the sleeve 21 rotates with nut 19, such rotation continuing .until 'the arms22 strike arms 27 and such rotation enabllng the filled pockets 7 to move away. from the point of supply and to a place of discharge. Immediately upon contact of arms 22 with arms .27, the sleeve 21' ceasesto revolvewith nutg19 and stops continues to rotate; V caused to travel relative to the gears. 9

Which are of course held stationaryby the shaft. 8, and the travel of the racks 10 is V such as to -force the pistons 12 outwardly and thus to discharge the divided dough from the filled pockets. The reciprocation bfithe pistons in the empty pockets is a mere incident The cylinder continues. 'to

"Trevolve until the formerly empty pockets are brought into-positionfor receiving a the rotatiton of shaft 8 while cylinder 1 Thus, the racks 10 are charge of dough and thereupon the operation is repeated. As the arms-22 by contacting with arms 27 reta1nsleeve21 against revolving with nut 19, the said sleevef21 during the rotation of cylinder 1, after contact of arms 22 with arms-27, is caused to travel axially inwardly by virtue of the threadslof nut 19. acting'on the threads of sleeve 21, and this axial travel of the sleeve continues until the arms 22 move inwardly beyond the transverse axial plan'e of the lnner extremity of arms 27 so as to leave the arms 22 free to revolve with sleeve 21 during the next pocketffilling-operation, the

angular movement of the arms'22 during the outward thrust of sleeve 21 incident to the inward thrust of the pistons by the force of the incoming dough occurring between the arms 27 and terminating short combination with a rotary cylinder having a dough receiving pocket, of a rotary shaft discharging the dough therefrom, of a memjournaled axially in the cylinder and adap't-' ed to be rotated independently of the rotation of the cylinder, a piston in the pocket, gearing connecting the piston with the shaft for rotating the shaft independently of the cylinder and for imparting-a thrust to the pistonwhen the rotation. of the shaft is interrupted and the cylinder continues to rotate, and means for interrupting rotation of the shaft while'the cylinder is rotating.
